BOX.

Application filed July 15 l This invention relates to a 'paper or-cardboard. box formed approximately in the shape of a horse shoe with its curved side wall extending around the curved outer side of the box conformingto the outer s1de of. a horse shoe, and an inwardly curved side wall portion-connecting the ends of Vsaid tirst side wall portion.

An object of the invention is to lmprove the construction of such boxby providing a side wall composed of 'a single piece of material having one edge 'attached to the top or the bottoni of the box and having its ends connected atone of the corners, and' iin proved means for strengthening the connection ofthe side wall with the top or bottom of the box throughout the length of the side wall.

Another object of the invention is to improve the 'construction of a. horse shoeshaped box whereby the manufacture Vor production of the boxes is facilitated,A and the cost of manufacture reduced and abetter `product obtained.

Other objects will appear from the following descripticn` reference being made to the drawing in which Fig. 1 is a plan view of my improved box with a part of the outer sheet being broken away to show clearly the construction by which the side walls are attached to the top and bottom of the box, respectively.

Fig. 2 is a sectional view on the line', 2-2 of Fig. 1.

Fig. 3 is a perspective view showing one of the inner corners of the box whereby the ends of the side walls are connected.

Fig. 4 is a perspective view showing one of the outer corners of the box.

The top and bottom of my improved box are of 'duplicate construction, except that-.the

side' wall of the top encloses a slightly larger area than the side wall of the bottom,. 'so that, when the top is placed on the bottom'. the sidewall of the top closely surrounds the vside wall of the bottom of the box. Since the top and bottom are of duplicate .construction with` this exception, adescription of one applies also to the other. and like reference numerals are applied to similar parts of the top and bottom of the box.

The topand bottom of the box each coinprises an outer section l' of cardboard or similar material 'having the. greater portion of its edge curving generally to resemble the .outer edgeeof a horseshoe, and having an 1927. serial No. 205,909.

inwardly curved portion formingthe edge intersecting the' outside curved portion and forming therewith sharp corners'2; and an inner sectiont3 of slightly smaller area than .60 the outer section 1, but of precisely the same i shape.

The outer wall of the bottom and the top' of the box,respectively, comprises an elongated strip 4 of cardboard or the like -of a 65 length slightly greater than' the distance aroundthe' innersection 3. At a distance from one longitudinal edge of thisstrip '4 a score line 5 is formed throughout the length of said strip and parallel with` its edg'e. I hat part of the strip between the score line-5 and the adjacent edge-is provided with'notches 6 extending to said score"- lineq most of which notches are approximate- 1y V'shaped and which are at varying dis- `75 tances apart, as' will be understood by 4reference to-Fig. 1. .The tongues 7 formedby these notches 6 are bent laterally-along the .score line 5 at right angles between theinner and outer bot-tom' and top sections Land 8U 3. so that the' walls 4 bear closely against the edges of the inner top and bottom sections 43. The outer edge 8 of the tongue .7 at the end of the wall 4 is cut onan incline 'and approximately bisects the angle 2 at the cor-' 35 ner of the box. In placing the wall 4 .about the inner section 3, the end 9 of the. wallA 4 A on which the tongue 7 isiormed, .as def. scribed, is positioned. at onelof the corners 2 of thesection 3; and' said wall 4 lis thenft` curvedv around the outwardly curved edge of the section 3 to the opposite cornei-` 2 of;

said Section where a tongue 10 similarin all respects Atothe tongue 7 at the opposite end of the wall 4,-is provided. From the corner '2- at-'which the tongue -1 0 is located,- the wall 4 is c-urved-inwardly'against the .inwardly curved edge of the -'section 3 to the opposite corner 2. there being tongues'll, the edges of two of which are close to thev edges of the adjacent tongues 7 and 10, respectively. -Beyond the end tongue 11 the wall4 of the box has an extension 12 bent at a sharp angle against and glued'to the inner side of the adjacent endof the wall 4 (Fig. 3). `-105 These tongues which overlap-the edge of the section 3 are secured thereto by blue and the section 1 is placed against the outer side of the section'3 and secured to the tongues of the side wall lby glue. t From afbeginning adjacentto the extension l2 the side wall 4 has an integral inl wardly bent .portion 13 extending-to the op? posite end ofthe wall 4 and, at itsl said op'- posite end, overlapping the extension 12.

' .This portion`13 of the side wall is defined listing objection.

a score line 14 extending throughout the length of the side wall and along which the portion 13 is bent inwardly, -as described.

Thus it will be seen'that I have provided' a horse shoe box -construction in` which 10 neither the top nor the'bottom is easily dev'tachable from the corresponding side wall and which, in this respect, overcomes an ex- The box may be manu,- factured by Abox making machines quite' 4rapidly and economically.

I claim:-

l. .A box comprising an` inside bottom forming sheet having an inwardly curving4 recess in one edge,and its remaining edge` curving continuously from intersectionfwith the ends of said recess and beingyof greater diameter in any direction than the width of `said recess, and 'forming sharp corners vat the intersection withsa'id recess; and a side for said box comprising an elongated strip having Anotches in one'edge, and-tongues eX- tending from' -said notches bent inwardly against the outer side of said bottom sheet,

one end of said strip being at one of said cor` Jners and the body of said strip 4being bent around the curved edge of said. sheet and against the edge of said -sheet in said recess,

' and having its other end overlapping the in- .ner side of said first end and secured thereto for a distance above the curved edge of said sheet,4 an infoldedportion along the upper edge and throughout the extent of said .wall and overlapping the overlapping portion of said wall, and an outside bottom forming sheet of the same-shape as'the inside bottom 'forming sheet secured to said tongues and having its edges extending'. beyond said wall.
